Why would you ever need something like this? To control all the undead corpses that have risen from their graves maybe? Or maybe it summons MJ to get that party going after you have exhausted all the usual tricks.
An Indian movie from the 80s, starring Amitabh Bachan, had him wear a similar gauntlet which could punch through walls, shield him from sword attacks and even help him dodge bullets. Could it prove to be a similar defense mechanism?
In any case, one of these mounted on your living room wall is sure to get lots of attention and be the topic of many an interesting conversation.
